spiffy

( /spiĀ“fee/, adj.)

   1.  Said  of  programs  having  a  pretty,  clever,  or exceptionally
   well-designed  interface.  "Have  you  seen the spiffy {X} version of
   {empire} yet?"

   2.  Said  sarcastically of a program that is perceived to have little
   more  than  a  flashy interface going for it. Which meaning should be
   drawn  depends delicately on tone of voice and context. This word was
   common mainstream slang during the 1940s, in a sense close to 1.
